Abstract

A mould for injection compression moulding of an article, comprises a female mould part (10) and a core (16) for mounting in use on the platens of an injection moulding machine for movement towards and away from one another between an open and a closed position. A sealing ring (20) surrounds the core 16 for effecting a seal between the female mould part (10) and the core (16). The core (16), the female mould part (10) and the sealing ring (20) together define a closed mould cavity as the core approaches the closed position. In the invention, the sealing ring (20) has a tapering surface (22) that seals against a tapering surface (26) on the core (16) only after the core has reached the closed position, leaving a venting clearance between the tapering surfaces (24, 26) of the sealing ring (20) and the core (16) as the core (16) approaches the closed position.
